Why Are There No Big Animals In Australia
The lack of volcanic activity is due to the islands location in relation to a tectonic plate the two layers of the Earths crust or lithosphere.
Why are there no big animals in australia. Yummie is not my reaction. This is because what became Australia split off and became isolated from the rest of the world about 55 million years ago. Our investigations within Australia and abroad have uncovered cruelty and forced needed change within once hidden industries including the live export trade factory farms and the greyhound racing and export industry.
It is a secluded landmass with no immigration of animals from other parts of the world. The distribution of climates topography and soils that has produced the zones and ecological variation of Australian vegetation has also been reflected in the distribution of animal life. But there is still so much we dont know about Australias native animals.
So an exceptionally large proportion of australias plants and animals are endemic meaning they naturally exist nowhere else in the world. Even though most modern zoos make efforts to offer animals a more natural environment most captive animals in zoos are unable to live in a way that they would naturally and some may even be on medication to alter their behaviour. However on the most fundamental level such incredible growth is impossible because there are no large animals exhibiting these ancient avian traits.
The famous list of Australia having nearly all of the worlds most venomous snakes comes from a terrible LD50 study that only. In Australia there are 8128 accepted described species known as chordate which include vertebrates as well as 98703 invertebrates 24716 plants 11846 fungi and around 4186 in other groups. Learning about Australias extinct fauna helps us to create links through time that relate the animals of the past with those of today and to develop conservation strategies.
Even though Australia and Asia are relatively close today they havent been connected since the supercontinent Pangaea broke up all that time ago. A grand total of 21 out of the worlds 25 most venomous snakes inhabit Australia. The earliest cat fossils date back only 10 - 15 million years so.
Australias coast also stretched further into the Timor Sea. Even though Australia is home to nearly 150 volcanoes none of them has erupted for about 4000 to 5000 years. Australia - Australia - Animal life.
